GHO, Aave’s native stablecoin, launched in mid-2023 with a straightforward pitch: borrow a protocol-owned stablecoin against your collateral on Aave v3, skip the middleman, let the DAO capture the interest. Eighteen months later, the supply sits well below targets, the peg has repeatedly drifted below $1, and the fixes applied so far have been reactive rather than structural.
The Peg Problem Is a Demand Problem
Most algorithmic or CDP-backed stablecoins break on the supply side - someone prints too much, backing collapses. GHO’s issue is the opposite. There isn’t enough reason to hold it.
When GHO trades below $1, the arbitrage mechanism depends on borrowers closing their positions - repaying GHO to unlock collateral. That works in theory. In practice, borrowers don’t close positions just because GHO is at $0.997. The discount isn’t wide enough to overcome gas costs and the friction of unwinding a leveraged position. So the peg restoration mechanism is sluggish by design.
Aave’s governance has responded by raising the GHO borrow rate, which reduces new issuance and theoretically tightens supply. It also introduced the GHO Stability Module, allowing direct USDC-to-GHO conversion with a small fee. These measures helped - GHO has traded closer to peg through early 2026 - but supply growth has stalled around the low hundreds of millions, far from the multi-billion scale Aave DAO projected.
The stkAAVE Discount Backfired
Early on, Aave offered staked AAVE holders a discounted borrow rate on GHO - an attempt to tie protocol governance participation to stablecoin demand. The problem: it created a pool of sticky, cheap borrowers who had little incentive to repay, and whose GHO often flowed straight into liquidity pools rather than being used as a medium of exchange. It inflated the borrower count without building real stablecoin utility.
The discount was later adjusted, but it illustrated a recurring issue in DeFi stablecoin design: incentive structures that look elegant in a whitepaper often produce weird user behavior at scale.
What Actually Needs to Change
GHO needs distribution - integrations where holding or spending GHO is preferable to USDC or USDT. That means payment rails, cross-chain expansion with genuine liquidity depth, and yield opportunities that don’t require users to stay inside Aave’s own ecosystem. Aave has announced cross-chain GHO initiatives using CCIP, but execution has been slow.
The underlying lending protocol remains one of the most battle-tested in DeFi. GHO’s weakness isn’t a reflection of Aave’s security - it’s a product problem. Building a stablecoin that competes with USDC requires more than a governance vote and a favorable borrow rate.
